Implementation method for adaptive variable slide receiving window of broadband signaling link

Abstract

This invention provides a broadband signal link adaptive variable sliding receiving window method, and firstly, the recipient estimates the initial value of the receiving window size, and according to the initial value, the sender sends the data packets; after the recipient receives the data packets sent by the sender, it temporarily store the data packets in the interrupt receiving buffer, the buffer size being X; and then, the recipient calculates the idle data packets number Y in the current interrupt receiving buffer, and processes receiving handling to all the accumulated data packets in the interrupt receiving buffer; when need to send the receiving window update information to the sender, the recipient calculates the average Y' of Y since the last receiving window update, and divides this average Y' by X, to get average idle ratio Z; according to the comparison of Z and preset threshold value, the recipient determines the adaptive changes of the sliding receiving window. Thus, the invention realizes the adaptive variable sliding receiving window.

Description

technical field [0001] The invention relates to a method for realizing a signaling system in the communication field, in particular to a method for realizing an adaptive variable sliding receiving window of a broadband signaling link. Background technique [0002] The receiving window is a mechanism provided by the SSCOP (Connection-Oriented Specific Service Protocol Layer) protocol for the receiving party to control the sending rate of the sending party and perform traffic adjustment. SSCOP is a link layer protocol (ITU-T Q.2110) of broadband SS7 system, which provides point-to-point reliable message transmission service and has been widely used. Its typical application protocol stack is shown in Figure 1. [0003] The basic principle of using the receiving window for flow control in the SSCOP protocol is as follows: the sending SSCOP entity encapsulates the signaling data transmitted by the SSCOP upper layer user request to the peer end into SD PDU (Sequenced Data Protoco...

Problems solved by technology

When the error is relatively large, it may affect the performance or quality of the link

[0018] 2. When the receiver's link receiving capacity or CPU processing capacity is insufficient, it is impossible to reduce the peer's sending traffic by dynamically reducing the receiving window, which will easily cause the receiver to save and process it too late, resulting in more retransmission of data packets. Increase the burden on the link and reduce the link quality evaluation
